'WATEEv-CLOSET STRUCTURE.

Application filed February 6, 1924.

To all whom it may concern:

Be it known that 1, ROBERT J. TVTGLAEF siding at lVoodlawn, in the county ot Beaver and State of Pennsylvania, a citizen oi the United States, have invented er discovered certain new and useful improvements in Water-Closet Structures, of which improvements the following is a specilication.

Tn Letters Patent of the United States No. 1,4l i7,028, granted me February 27th, i923, tor improvements in water closets, T have described and claimed certain ventilation features. My present invention. concerns further improvements thereon.

My present invention is illustrated in the accompanying drawings in which Figure I is a view in vertical and longitudinal sec tion, on the plane indicated by the line I-.l, Fig. TH. Figure IT is a view in vertical section, on the plane indicated at TI ll, Fig. TH. Figure HT is view in plan from above. Fig. TV is a view similar to Fig. T, the plane of section being medial throughout. and illustrating a modification.

The water closet here shown, and it is with water closets of this particular type with which my invention has primarily to do, if. rthenware fixture which includes in a single, integral piece a bowl 1 and a siphon pipe The bowl opens from the bottom to the siphon pipe, the bend in the siphon pipe defines the level (indicated by the dotted line (/.-r;:, Fig. I) at which water normally stands in the fixture, and the siphon pipe ends in a lead opening from the l ise of the fixture, with which lead con nection may be made with a soil pipe.

An opening 4 is formed in the bowl, in its upper part, through which the flushing stream may gain ingress, and connection is made with a flushing pipe 5, to carry the flushing stream from a tank or other water supply. The flushing stream of water, descending through the flushing pipe 4, passes through the bowl and out through the siphon pipe, and in so doing sets up the siphon action from bowl to soil pipe which is characteristic of water closets generally.

In the practice of my invention the flushing pipe instead of opening directly to the bowl of a water closet, opens into an intermediate chamber 6 which in turn opens through the orifice 4 into the bowl 1. This intermediate chamber is, when the closer- Serial NO. 690,926.

is idle, filled with air, and when the closet is being flushed, it is part of a passageway through which the stream of water flows. it is, as is best shown in Figure 1, formed integrally with bowl and siphon pipe, as a cavity or chamber in the piece of earthenware. My prior patent alluded to above describes and claims a branch pipe which leads from the flushing pipe, and from a point adjacent its delivery end, to any suitable escape, which may be the soil pipe or some other place of escape. In this branch pipe a nozzle is arranged. Two valves are provided, one controlling the opening of the branch pipe, the other controlling the flow of water to the nozzle, and both of these valves move in response to movement of the watercloset seat, so that when the seat is depressed the ventilation pipe opens and a flow-impelling jet of liquid is caused to spurt longitudinally within this branch ventilation pipe, and so a ventilating stream of air is temporarily caused to flow from the bowl through the branch pipe to the place of escape.

My present invention consists in provid' ing as an integral part of the water closet structure, on one, or it may be on both sides a by-pass leading from the chamber 6 above to the siphon pipe 2 below, and at a point lower than the level at which water comes to rest in the bowl 1. That is to say, lower than the bend of the siphon. This lay-pass or these by-passes 7 are formed integrally and in one piece with the rest of the fixture.

Within this by-pass 7 is arranged the valve 8 which, when closed, is water sealed, as is illustrated in Figure I.

Within the by-pass and below the valve 8 is arranged a water nozzle, 9. Conveniently the water pipe 10 which terminates in the nozzle 9 constitutes the stem of valve 8.

The seat 11 of the water closet is hinged as is usual and normally is held, as by a spring 12, slightly elevated. Depression of the seat in service elevates the pipe-length 10 and unseats valve 8. The elevation of the pipe-length 10 also opens a valve, indicated at 13, causing a. stream of water to flow through the pipe and to spurt in a jet from nozzle 9.

By such means, the chamber 6 being at the time empty, depression of the seat sets up the flow of a ventilating stream of air from the bowl, through chamber 6; and by-pass even under such circumstances, the normal I flushing operation. The modification Sl10W11l11'F1g. IV consists only in this, that'the by-pass 7, 1n-

stead of being laterally arranged, and perhaps in duplicate, on the two sides, is medially arranged at the rear. As in the form first described, it is -formed in one piece of earthenware with the other chambers and passageways of the fixture, and its connections are identically the same. One arrangement or the other may be chosen, to suit the space where installation is to be made.

I claim as my invention:

1. An integral water-closet fixture within which are formed a water-closet bowl, a chamberopening to the bowl, a siphon pipe opening from the bowl, and a by-pass opening from the chamber first named to the siphon pipe at a level lower than the bend of the siphon, av swinging seat for the bowl,

provision for connecting a flushing pipe directly to the chamber above ment1oned,and provision for connecting thesiphon pipe to the soil pipe, a valve in the by-pass and a nozzle in the by-pass and means operative on the swinging of the seat for opening the said valve and "for propelling av jet of fluid from said nozzle. V

2. In a water-closet structure the combination of a water-closet bowl, a flushing passageway leading to saidbowl, a siphon passageway leading from said bowl, a bypass leading from flushing passageway to siphon passageway, a. valve in said by-pass carried on a pipe-length which pipe-length below said valve terminates in a nozzle, a swinging seat for said water closet, said seat and said pipe-lengt11 being interconnected, whereby on the swinging of the seat to service position the pipe-length is elevated and the valve unseated' and water is caused to flow through said pipe and from the nozzle.

In testimony where'oilhave hereunto set my hand. I i l ROBERT J; MOLANAHAN,
